She quit teaching, works at Costco, and has 'never been happier.' That says something.

Maggie Perkins' viral videos and unique perspective have ignited the conversation around teacher attrition.

Maggie Perkins doesn't miss having a winter break.

Maggie Perkins loves teaching, loves teachers and loves students. In fact, she loves them so much that working on her Ph.D. in Educational Theory and Practice. Her research is focused on teacher attrition, examining why quality, experienced teachers quit the profession—something she understands all too well since she recently became one of them.

The former educator now works at Costco and she says she's never been happier. Her migraines are gone. Her anxiety has improved. She sleeps through the night. As an entry-level employee, she makes less money than she did teaching, but not enough less to make a difference in her financial situation. She goes home from work happy at the end of the day.

Perkins has been sharing the contrast in working conditions between the classroom and Costco on her TikTok channel and it is eye-opening, to say the least.


To be fair, Costco is known for employee satisfaction. They take good care of their people with solid wages and benefits, and as a result, they have an impressive 94% retention rate for employees who stay longer than a year. That's incredible for a retail business. And it's not just about their comparatively generous compensation package. Perkins has shared in several of her videos how she feels respected and valued as an employee at Costco—far more than she did as a teacher working in various schools, teaching various grades in two different states.

People often assume that the biggest reason teachers quit is inadequate pay, but compensation is just one piece of the teacher exodus puzzle. Perkins makes it clear that teachers should definitely be paid more, but attrition isn't just about money. It's often a result of burnout caused by a multitude of factors, including lack of time and support to do the job they are trained to do, the twisted way the teaching profession is viewed and valued by society and the pile-on of additional duties teachers are assigned to do besides teaching.

Today I was on Varner & Co with 🦊. This is the full segment. It feels short, but they managed to squeeze me in between a study about it cheese causes nightmares and the woke 👮‍♀️ adding pants to a root beer mascot. It was my pleasure to make a contribution.

Let's look at the time element alone. Planning is a big part of teaching, especially if you're trying to meet individual students' learning needs, yet teachers are rarely given the amount of planning time they need. On top of that, the time they do have is often usurped by other things.

"Let's say you have a fight in your classroom," Perkins tells Upworthy. "Well, then you just lost 45 minutes of your planning because you're going to have to be in the front office doing documentation, calling people. You just lose your day. There's so many different ways to lose your whole day, and then you end up either taking work home or making hard choices about what to let go, like you're juggling glass and rubber balls and you have to figure out which ones are glass and which ones are rubber. Like, what can you let drop?"

Tonight when I walked out of work, I felt happy. I felt happy because I enjoyed my work, my coworkers and felt good about my job. When I was a teacher I only felt good leaving work *because I was leaving* the building. Yes, of course, there were *things* I enjoyed about the job, but being a teacher was so much more than teaching, and the anxiety inducing parts of the job were shredding me. Education as a whole is an environment of scarcity. From the resources to the ways teachers are treated. Costco is run in a way that operates from a place of generosity and genuine care. It’s amazing to me that a multi billion dollar company can exude this for its members and employees but the education system cannot. #formerteacher #teacherquittok #costcotiktok #retailworker #exteachertiktok #formerteacher #scarcitymindset #costcodoesitagain

A big misconception some people have about teaching is that it's easier than other professions because you have long holiday breaks and summers off. Some even go so far as to use the word "cushy." Plenty of teachers have refuted that notion, showing how many hours they actually work outside of official work hours or how they have to work two jobs to not be living paycheck to paycheck.

"If you're coming at teachers being like, oh, you have a cushy job, then you work it," says Perkins. "If you think it's so soft and so cushy, it has so many amazing benefits, then come on over and work this job. More of us should be lining up for it."

"But if we have a teacher shortage, how can it be that cushy of a job?" she adds. The reality is that people who have never worked in a classroom have no idea how relentless and stressful it can be on multiple levels, even when you love teaching and love your students.

Here Perkins describes what it was like working a 7-day shift during the holidays instead of having that cushy winter break:

@millennialmsfrizz

I used to be a teacher and now I work at Costco. This is my first year not having a winter break. I do not miss it at all. My pace of my work life now is so much better, I am not sick or exhausted like I used to be when I was a teacher. When I was a teacher I used my winter break basically to recover and go into the next semester of just surviving. #f#formerteachert#teacherquittokc#costcotiktokr#retailworkere#exteachertiktokc#careertransitiont#teachersonbreak

Perkins points out that we don't actually have a teacher shortage, but rather a teacher exodus. There are plenty of qualified, credentialed teachers who have simply given up trying to make the career they love actually sustainable.

Many people have put forth suggestions for various school reforms, but those who have seen the problems from the inside know they are layered, widespread, systemic and deeply ingrained. Perkins tells Upworthy she believes the school system needs a complete overhaul.

"I think we will be forced into it," she says. "But I don't think that'll happen for at least 10 years. I think things are going to get much worse before they get better."

@millennialmsfrizz

If you are new to this account, you should know that the issues I discuss are things I’ve experienced at several schools, grade levels and in different states. These are systemic issues, and are getting worse, not better. But, welcome, I suppose, and I hope you feel seen, known and appreciated because you are. #teachersoftiktok #formerteacher #teacherquittok #educatedexit #KAYKissCountdown #educationcrisis #teachershortage

She says focusing more on teachers and students would help alleviate some of the "crash and burn" she sees coming, or perhaps even help prevent it. But some major changes would have to take place for that to happen.

"A teacher who has six class periods with 35 students in them? That person cannot possibly deliver quality instruction to all of those students all day. And then have one planning period to grade, plan, et cetera. It's just it's impossible."

She says reducing class sizes, increasing planning periods and eliminating extra duties such as carpool duty, hallway duty and other seemingly small things that chip away at a teacher's time are immediate changes that can and should be made. But school administration is often more focused on testing, data, and resources than on what students and teachers themselves need to create a healthy, sustainable learning environment.

Then there's the issue of how teachers are viewed. Outright disrespect is one thing teachers face, but even well-meaning people who think they are supporting teachers can contribute to the problem.

For instance, Perkins explained in a video that she doesn't call teachers "heroes" anymore because it's a loaded term that leads to a martyrdom mindset. After all, heroes fulfill the mission, no matter how hard it gets, right? Heroes are ready and willing to sacrifice it all for the cause. Most people who refer to teachers as "heroes" do so as a compliment, but when you really break down what that term means, it sets an expectation that teachers will do the job no matter how bad it gets, sacrificing themselves and their own well-being because their profession is a "noble" one. That's not just unfair; it's abusive.

@millennialmsfrizz

Teachers are called heros. Teaching is regarded as a noble profession, a higher calling. Teachers should be able to work in conditions that do not require heroic sacrifice. Teachers should be able to do their job in a normal way without suffering, sacrificing, defend for themselves etc. #teachersoftiktok #teacherquittok #teachersareheroes

"The thing that I most want to communicate in my videos is that teaching is not a 'noble profession.'" Perkins tells Upworthy. "It's a job, and people should be paid for the job that they do and respected for the work that they do, and that by attributing nobility to the profession, you assign to teachers this emotional labor of the whole culture, of the whole society."

"When we do that, we add to them additional responsibility above and beyond their actual jobs," she adds. "And then that allows people to degrade the profession by saying basically we pay you with emotion. Like we say, 'You're heroes!' and we get in the cycle of praising them for what they do, and then gaslighting them for what they fall short on. But what they're falling short on is stuff that was never their job in the first place."

Perkins also wants teachers to know that they have transferable skills and that they don't have to put up with a poor quality of life when they can find a higher one in a different profession.

"I see so many teachers like myself even feeling trapped or feeling limited, like teaching is the only thing we can do," she says. "And then when they go into other professions, they're wildly successful. They rise to the top in their career fields. They are good employees and they enjoy the quality of their life as well."

"I want to communicate to teachers—you're not stuck, you don't have to be afraid, your quality of life matters, and it's not selfish to transition your career, because a lot of teachers stay in it, too, because they don't want to feel like they're failing the students."

quiet, finger over lips, don't talk, keep it to yourself, silence

A woman with her finger over her mouth.

It can be hard to stay quiet when you feel like you just have to speak your mind. But sometimes it's not a great idea to share your opinions on current events with your dad or tell your boss where they're wrong in a meeting. And having a bit of self-control during a fight with your spouse is a good way to avoid apologizing the next morning.

Further, when we fight the urge to talk when it's not necessary, we become better listeners and give others a moment in the spotlight to share their views. Building that small mental muscle to respond to events rather than react can make all the difference in social situations.

What is the WAIT method?

One way people have honed the skill of holding back when they feel the burning urge to speak up is the WAIT method, an acronym for the question you should ask yourself in that moment: "Why Am I Talking?" Pausing to consider the question before you open your mouth can shift your focus from "being heard" to "adding value" to any conversation.

The Center for The Empowerment Dynamic has some questions we should consider after taking a WAIT moment:

  • What is my intention behind what I am about to say?
  • What question can I ask to better understand what the other person is saying?
  • Is my need to talk an attempt to divert the attention to me?
  • How might I become comfortable with silence rather than succumb to my urge to talk?

The WAIT method is a good way to avoid talking too much. In work meetings, people who overtalk risk losing everyone's attention and diluting their point to the extent that others aren't quite sure what they were trying to say. Even worse, they can come across as attention hogs or know-it-alls. Often, the people who get to the heart of the matter succinctly are the ones who are noticed and respected.

Just because you're commanding the attention of the room doesn't mean you're doing yourself any favors or helping other people in the conversation.

The WAIT method is also a great way to give yourself a breather and let things sit for a moment during a heated, emotional discussion. It gives you a chance to cool down and rethink your goals for the conversation. It can also help you avoid saying something you regret.

How much should I talk in a meeting?

So if it's a work situation, like a team meeting, you don't want to be completely silent. How often should you speak up?

Cary Pfeffer, a speaking coach and media trainer, shared an example of the appropriate amount of time to talk in a meeting with six people:

"I would suggest a good measure would be three contributions over an hour-long meeting from each non-leader participant. If anyone is talking five/six/seven times you are over-participating! Allow someone else to weigh in, even if that means an occasional awkward silence. Anything less seems like your voice is just not being represented, and anything over three contributions is too much."

Ultimately, the WAIT method is about taking a second to make sure you're not just talking to hear yourself speak. It helps ensure that you have a clear goal for participating in the conversation and that you're adding value for others. Knowing when and why to say something is the best way to make a positive contribution and avoid shooting yourself in the foot.

Real people share 17 red flags that expose someone trying to appear wiser than they actually are

"Actually referring to oneself as 'smart' in general is often a good indicator too."

low intelligence, low iq, iq lower, signs of low intelligence, not smart, not very smart

A man looks confused.

People who struggle with intellectual functioning, often described as having a low IQ, may also be considered to have low intelligence. Determining low intelligence is not always easy or obvious, so people on Reddit shared their thoughts on the signs that can indicate it.

One observant Redditor shared their insight, writing that a sign of low intelligence is "actually referring to oneself as 'smart' in general is often a good indicator too." The comment is an example of the Dunning–Kruger effect, first described in 1999 by psychologists David Dunning and Justin Kruger, which found that people with lower IQs tend to overestimate their intelligence, while those with higher IQs often underestimate it.


"Those with limited knowledge in a domain suffer a dual burden: Not only do they reach mistaken conclusions and make regrettable errors, but their incompetence robs them of the ability to realize it," the psychologists wrote, according to Psychology Today.

17 signs of low intelligence, according to Redditors

"When presented with an statement that generalizes something, they will use an anecdote as a counterexample and think that it completely refutes the statement. Example: travelling in an airplane is generally safer than in a car. 'Actually that's not true, I know someone who died in an airplane crash.'" - Traditional_Rub_9828

"Refusal to learn, grow and change your views from evidence provided." - Userdataunavailable

"Confusing 'being loud' with 'being right.' The loudest person in the room is rarely the smartest." - Kernel_Slasher

"Actually referring to oneself as 'smart' in a general is often a good indicator too." - loku_gem

"Believing anything they see on social media." - Fabulous_Ady

"Lack of curiosity. Thinking they know it all." - Disastrous-Sky-8484

- YouTube www.youtube.com

"Further than a lack of curiosity is never asking questions. It was something I heard about gorilla researchers who taught them sign language that in the years of gorilla sign language communications they never had a gorilla ask a question of a human. That simple process of recognizing you don't know/have something you want, understanding someone else likely does know what you want, and asking them actually takes a lot of brain power. Some parrots and exceptionally smart dogs can hit that threshold... And some very cognitively limited humans do not." - MildGenevaSuggestion

"They get annoyed by people who act curious, too. About anything. 'Why do you care?' 'Who cares?' Idk man, it's just interesting. Why shouldn't I care?" - Belle_Juive

"Not realizing that everything has nuances." - SecretHuckleberry720

"Refusing to consider they might be wrong." - Marry_Ennaria

"Not being able to understand or engage with hypotheticals. It is a meme online but that is actually a sign of low intelligence. Individuals with IQs under 90 often struggle with conditional hypotheticals—such as 'How would you feel if you hadn't eaten dinner?'—responding with factual rebuttals like 'But I did eat dinner.'" - Emergency-Resist-730

@baxate_carter

Even more low IQ traits from a year ago

"Severe impairment in metacognition - that is, a persistent inability to recognize one's own errors in thinking, monitor one's own reasoning, or adjust beliefs/behavior even when presented with clear contradictory evidence." - DiamondCalvesFan

"Ironically, Always having an answer. There is a lot of power in saying 'I don't know'." - Loose-Cicada5473, mattacular2001

"People who mock others instead of trying to understand them. Curiosity is usually a sign of intelligence." - cutiepie_00me

"Repeating the same mistakes and blaming everyone else." - Luckypiniece

"Bragging that you haven't read a book since high school." - tiger0204

"One move chess player. This is like an analogy to how some people think and act and vote. A good chess player is thinking 3 or more moves ahead. a bad one is playing one move ahead only. When people say things like 'Why should I pay school taxes if I don't have any kids!?' they are playing one move without thinking ahead. Better schools means a more educated populace means less crimes and more economic opportunity for your area, thus it benefits everyone whether they have kids or not." - ChickenMarsala4500

arthur c. brooks, harvard, psychology, happiness research, bucket list

Harvard researcher Arthur C. Brooks studies what leads to human happiness.

We live in a society that prizes ambition, celebrating goal-setting, and hustle culture as praiseworthy vehicles on the road to success. We also live in a society that associates successfully getting whatever our hearts desire with happiness. The formula we internalize from an early age is that desire + ambition + goal-setting + doing what it takes = a successful, happy life.

But as Harvard University happiness researcher Arthur C. Brooks has found, in his studies as well as his own experience, that happiness doesn't follow that formula. "It took me too long to figure this one out," Brooks told podcast host Tim Ferris, explaining why he uses a "reverse bucket list" to live a happier life.


bucket list, wants, desires, goals, detachment Many people make bucket lists of things they want in life. Giphy

Brooks shared that on his birthday, he would always make a list of his desires, ambitions, and things he wanted to accomplish—a bucket list. But when he was 50, he found his bucket list from when he was 40 and had an epiphany: "I looked at that list from when I was 40, and I'd checked everything off that list. And I was less happy at 50 than I was at 40."

As a social scientist, he recognized that he was doing something wrong and analyzed it.

"This is a neurophysiological problem and a psychological problem all rolled into one handy package," he said. "I was making the mistake of thinking that my satisfaction would come from having more. And the truth of the matter is that lasting and stable satisfaction, which doesn't wear off in a minute, comes when you understand that your satisfaction is your haves divided by your wants…You can increase your satisfaction temporarily and inefficiently by having more, or permanently and securely by wanting less."

Brooks concluded that he needed a "reverse bucket list" that would help him "consciously detach" from his worldly wants and desires by simply writing them down and crossing them off.

"I know that these things are going to occur to me as natural goals," Brooks said, citing human evolutionary psychology. "But I do not want to be owned by them. I want to manage them." He discussed moving those desires from the instinctual limbic system to the conscious pre-frontal cortex by examining each one and saying, "Maybe I get it, maybe I don't," but crossing them off as attachments. "And I'm free…it works," he said.

- YouTube www.youtube.com

"When I write them down, I acknowledge that I have the desire," he explained on X. "When I cross them out, I acknowledge that I will not be attached to this goal."

The idea that attachment itself causes unhappiness is a concept found in many spiritual traditions, but it is most closely associated with Buddhism. Mike Brooks, PhD, explains that humans need healthy attachments, such as an attachment to staying alive and attachments to loved ones, to avoid suffering. But many things to which we are attached are not necessarily healthy, either by degree (over-attachment) or by nature (being attached to things that are impermanent).

"We should strive for flexibility in our attachments because the objects of our attachment are inherently in flux," Brooks writes in Psychology Today. "In this way, we suffer unnecessarily when we don't accept their impermanent nature."

What Arthur C. Brooks suggests that we strive to detach ourselves from our wants and desires because the simplest way to solve the 'haves/wants = happiness' formula is to reduce the denominator. The reverse bucket list, in which you cross off desires before you fulfill them, can help free you from attachment and lead to a happier overall existence.

A lighthearted moment turns bittersweet with a painful realization.

Parenting is full of bittersweet moments. Every milestone toward independence—walking, talking, the first day of school—marks the end of something precious and fleeting, a time when parents are their children's entire world. So while these firsts are, of course, joyful, it's completely natural for parents to feel a sense of grief.

One such moment happened recently for Nick Gorman while he was filming his daughter playing in a puddle for the first time.


The now-viral clip, posted to TikTok, seems lighthearted enough. Gorman encourages his little one to splash in the water, and when she does, he gushes, "You know what this means? You're officially a kid. You're no longer a baby."

The phrase clearly hit harder than Gorman thought it would, because in the caption he wrote, "Well that realization hurt."

@nick.gorman8 Didn’t realize what I’d said until I watched the video later on…woof! #kiddos #toddlersoftiktok #aww #kidsoftiktok #dad ♬ These Memories - Hollow Coves

It's a realization that's pretty darn universal, as indicated by the thousands of other parents who chimed in on the TikTok video with their own similarly wistful stories:

"Today I heard my daughter getting into the Pop-Tarts while I was doing the dishes and dried my hands waiting for the inevitable 'daddy will you open this?' And then minutes went by, and silence. Curious, I poked my head around the corner and saw her eating them happily. She saw me and announced that she did it herself. I was so proud. But I still move the box up another shelf because I am not ready to stop helping her."

"My daughter used to call ketchup 'dip dip.' One day I asked if she wanted dip dip and she said 'it's ketchup mom.' My heart broke."

"My daughter used to hide from me when I'd get home from work. Came home expecting some elaborate hiding spot but she was just watching tv."

"One day I realized my babies quit calling me dada, and started saying daddy, and that was hard, but when I realized they had switched from daddy to dad that one had me in tears."

Experts seem to agree that when it comes to navigating these closing chapters, parents should permit themselves to feel whatever conflicting emotions arise and remember that it's a natural part of the process.

It's also important to remember that good things are still on the horizon. Every season brings its own special gifts and cherished memories. Even when kids finally leave the house to start their own adult lives, arguably the most bittersweet transition of all, parents are given the chance to explore other aspects of their identity that may have gone dormant during the more active days of parenthood.

Even Gorman seems to have recognized that his realization isn't entirely painful. In an interview with Newsweek, he shared, "While it's sad she's growing up, and we're already seeing our time with her pass, it's exciting at the same time to see her grow and experience new things—which is why I wanted to become a parent in the first place."

Nobody becomes a parent expecting things to become simpler. But most would argue that the trade-off is beyond worth it. And stories like these can remind parents that they're not alone in whatever feelings they're experiencing.

Researchers tested 6 brands of bottled water against tap water, and there was a clear winner

New technology allowed them to analyze the water in ways they never could before.

Ever since bottled water became popular in the 1990s, there has been a vigorous debate over whether it's healthier to drink bottled water or tap water. Bottled-water aficionados often claim it's purer than tap water because it's traditionally marketed as being "from the source" or having come from an untouched stream. That has to be cleaner than water that reaches your home after traveling from God-knows-where through city pipes, right?

What many people don't realize is that bottled water isn't regulated as stringently as tap water. Tap water is overseen by the Environmental Protection Agency (EPA), which requires more frequent testing and stricter disinfection standards. Bottled water is regulated by the Food and Drug Administration (FDA) as a food product.


Tap water found to have fewer microplastics than bottled water

A recent study from The Ohio State University (OSU) delivered another big victory for Team Tap, finding that after testing six brands of bottled water against tap water from four water treatment plants, bottled water contained more than three times as many microplastics as tap water. The big problem is that plastic bottles can shed tiny plastic particles, smaller than a speck of dust, into the water when temperatures change, the cap is removed, or the bottle tumbles around in a purse or the back seat of a car.

tap water, kitchen water, boy drinking, thirsty boy, kitchen sink A boy drinking from the kitchen sink.via Canva/Photos

The tests revealed that the amount of microplastics in bottled water ranged from 2.6 to 11.5 million particles per liter, while tap water ranged from 1.6 to 2.6 million particles per liter. In the best-case scenario, tap water contains similar levels of microplastics, but in the worst-case scenario, bottled water contains more than seven times as many.

The researchers were surprised by their findings because nanoplastics are so small that they've been hard to quantify in the past.

"This lack of knowledge primarily reflects limitations in the methods to isolate and analyze the nanoplastics," said Megan Jamison Hart, a PhD candidate at OSU and the study's lead researcher. "In this study, we developed and validated a novel method for isolating MNPs [micro- and nanoplastics], allowing for the determination of their concentrations using scanning electron microscopy and identification using optical photothermal infrared spectroscopy (OPTIR)."

Are microplastics harmful to humans?

Much more research on microplastics is needed to determine their potential harm to humans. Studies have linked microplastics to impaired immune function, increased inflammation, and cellular damage in animals. Researchers believe that larger nanoplastics pass through the digestive tract and are eventually excreted. Smaller nanoplastics, however, may move into human tissues and even enter the brain.

"While we don't really fully understand the human health risks associated with nanoplastic exposure, it's still better to try and mitigate that risk because evidence indicates that they do cause problems, even if we're not fully aware of what those are yet," said Hart.

Given that scientists have yet to determine the harm that micro- and nanoplastics can cause in our bodies, they believe it's best to avoid them as much as possible.

"We can make educated choices to try and reduce our daily exposure to these harmful chemicals," said Hart. "For the average person who is thirsty and wants a drink, the best way to do that would be drinking it straight out of the tap rather than grabbing pre-bottled water."

Hart told StudyFinds that the best thing to do is ditch bottled water and instead drink filtered tap water from a reusable metal bottle.

"This has definitely changed my own drinking habits," she said. "I was primarily a tap water drinker before, knowing that disposable bottles were bad for the environment, but this is something I am even more adamant about now, and I swapped my reusable plastic bottle for a reusable metal one."
